Sharing a portage tree (the files in /usr/portage) is perfectly safe, as this is identical for basic gentoo systems (prefix and similar are ...different. Best not go there ;-). However, the eix database is not portable between different systems. I do not have an exhaustive list of what settings cause incompatibility, but at least different ARCH (amd64 or arm) will cause issues since different packages are available to each. > Especially with the ARM I need to sync once a day, since I have to > limit the amount of software to be recompiled/updated after each sync > since the ARM is not *that* fast (for example a kernel compilation > take ~8h). While that is not strictly enforced, I myself run an rsync server locally, mostly to ensure that different systems have identical trees, thus preserving my sanity. Instructions for setting up a local rsync server can be found here: https://wiki.gentoo.org/wiki/Project:Infrastructure/Rsync To make a client (the arm box) sync from the local server, just change the sync-uri variable in /etc/portage/repos.conf/gentoo.conf and the SYNC variable (if present) in make.conf . You could even share a portage tree over nfs or similar, which I sometimes do for VMs. Depending on your (networking and storage) hardware, that might even work out favourably performance-wise. You could also generate a squashfs image on the desktop and transfer that to and mount it on the arm box (over http or something using a short shell script), if, say, the arm box is limited on storage space. A squashfs of the gentoo tree is about 70MB. -- eroen
